This book was released on 2018-03-29 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Recent Changes in Channel-Stored Sediment, Redwood Creek, California Historically, geomorphologists have studied both hillslope erosion processes and sediment transport in rivers, but few studies have quantified a link between these two areas the storage component of channels. Channels may temporarily store sediment derived from hillslope erosion before transporting it out of the system. The quantity of sediment and its residence time varies with the type of system. Streams in steep mountainous terrain store little sediment for relatively brief periods of time, whereas rivers in broad alluvial valleys store vast quantities of sediment in their floodplains for thousands of years. As a result, channel storage may modify the effects of hillslope erosion on sediment yield measurements made at a point downstream. Thus sediment yield measurements may not truly reflect current rates of hillslope erosion in a watershed. Nevertheless, changes in sediment yield are often used to detect changes in rates of hillslope erosion due to land use modifications. In basins where channels store a significant portion of sediment in transport, it is not valid to assume a constant relation between hillslope erosion and sediment yield because the amount of alluvial storage can change in response to modifications in a watershed.

Book Synopsis The Influence of Land Use on Sediment Quality in the Mill Creek Watershed by : Shadrack Ampomah
Download or read book The Influence of Land Use on Sediment Quality in the Mill Creek Watershed written by Shadrack Ampomah and published by . This book was released on 2018 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aquatic ecosystem of Mill Creek Watershed (MCW) is currently susceptible to pollution from nutrients and heavy metals due to the various human activities within the watershed. Sediment quality parameters such as trace metals, organic matter (OM%), pH, total phosphorus (TP) and particle sizes were measured at 13 sampling points along Mill Creek. The overall objective of the research was to determine the immediate land use around each of the 13 sampling sites and how that impacts the sediment quality. Each of these sampling points were used as watershed outlets to delineate 13 distinctive drainage areas, with their individual land uses. The results showed most of the parameters measured were within acceptable values. TP values within the southern watershed were higher than all other sites (MacDonalds et.al, 2005). These observations were explained by the land use of the delineated drainage areas around each of these sites. Site 9 had about 30% of its drainage area covered by agricultural land row crops, site 10 had 20% and site 8 had 14%. Agricultural runoffs may have played a role in the TP concentration. A more direct impact may be the location of the Boardman Waste Water Treatment Plant at site 8, the semi buffered cattle ranch located by the creek at site 9 and the crop farm located at site 10. Geospatial statistical maps created showed the northern portions especially site 2A and 4 as well as some middle areas of the watershed which include mostly site 8, 9 and 10, to have higher levels of most of the trace metals compared to the sediment reference values. The calculated correlations among percentages of land use, trace metals, TP, pH & OM%, showed Ba to be statistically significant to agricultural land use. TP was also positively correlated with agricultural land use but not statistically significant. pH was significantly correlated residential areas. The other trace metals were not statistically significant with any land use which may be because of the dominant sandy particle sizes and flow dynamics of the river. The predominant residential land use and CSOs locations were perhaps the contributing sources. Ongoing studies would benefit from analyzing samples in both dry and wet seasons, and after precipitation events. Researchers may have to Incorporate sediment texture properties when sampling. Researchers may also combine Soil and Water Assessment Tools (SWAT) with sediment geochemistry to model trace metals and TP loadings if Mill Creek watershed establishes a gauge station on its main-stem.These will augment the understanding of the relationship between human activities, sediment and water quality and the importance to ecological health.

This book was released on 2018-03-19 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Research and a Land Management Model for Southern California Watersheds Emergency sowing of herbaceous plants soon after a fire is an accepted practice in southern California watersheds. The purpose of this first aid treatment is to establish a temporary cover for protection of the watershed while the brush is slowly re covering. Although reasons for sowing denuded watersheds are obvious, the effects of sowing have never been quantitatively measured. Does the added cover pay in terms of reduced sedi ment in the stream channels? Are more expensive and more effective revegetation measures justified? The burned water sheds of the experimental forest should answer these questions. Annual species are usually sown because annuals are hardy and rese'ed themselves each year. The seed is abundant and cheap. For years black mustard was the most commonly sown species. In the last 6 years it has been largely replaced by common ryegrass in southern California, but on San Gabriel water sheds the two species have been sown in mixtures. Two other annuals-wimmera ryegrass and Blando brome-are now being used in some sowings. Which of the annuals provides the best cover on different sites? This is another question being studied. Deep - rooted perennial grasses also have been suggested for emergency temporary cover. They are commonly sown where permanent cover is desired, but perennials have never been widely tested on burned-over southern California watersheds. They are now being compared with annuals in the experimental watersheds to see if they provide better cover, especially at upper elevations too cold for good growth of annuals. The comparisons include tests of individual species and mixtures of species as both emer genoy and permanent cover. From October 23 to November 29, a total of acres were sown by helicopter within and adjacent to the experimental forest. An additional 83 acres were sown by hand, and 29 acres were sown with a heavy duty rangeland drill. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural Best Management Practices (BMPs) have been employed for years as erosion reduction measures on cultivated lands. The ability to model the effects of BMPs at the watershed scale using a standardized process-based method provides watershed managers with an important decision making tool for addressing large-scale water quality concerns. This study uses a process-based BMP simulation method with the Soil and Water Assessment Tool (SWAT) to evaluate five BMPs including grassed waterways, channel stabilization structures, strip crops, cover crops and vegetative filter strips on almond orchards in northern California, USA. The sediment reduction rate of the five BMPs was compared to a base case where no BMPs were applied to the watershed and analyzed for several precipitation scenarios to compare BMP effectiveness. In-channel BMPs which included grassed waterways and channel stabilization structures, reduced sediment load at the watershed outlet by 8% to 14%, respectively, depending on the annual precipitation scenario. Grassed waterways consistently outperformed channel stabilization structures, reducing sediment load by an additional 2% to 5% compared to channel stabilization structures. Upland BMPs including strip crops, cover crops and vegetative filter strips reduced sediment yield by 15 to 100% for the various precipitation scenarios. For years with median and above median precipitation, strip crops were most effective, reducing sediment yield by 63% in both cases, whereas cover crops only reduced sediment yield by 54% and 15%, respectively. For the below median precipitation year, the cover crop reduced sediment yield from fields completely (100%), whereas strip crops and vegetative filter strips only reduced sediment load by 64% and 59%, respectively. For all BMPs, a positive correlation between sediment load/yield and increasing precipitation amount and intensity was observed. The methods presented in this study are easily applicable to watershed scale studies of other basins and for other water quality concerns, such as the fate and transport of agricultural pesticides and nutrients.
