Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Mau forest complex has experienced forest destruction to make room for cultivation from as early as 1970s. This has had a disastrous effect on forest cover. The changing land use has resulted in reduced water retention capacity and increased soil erosion in the catchment. Consequently very large peaks and low flows with frequent drying up in the lower reaches are common in River Njoro. Due to increased erosion, the river deposits so much sediments into Lake Nakuru. The study investigated the effect of rainfall intensity on soil erosion and surface runoff on different land use practices. Field rainfall simulation at different rainfall intensities was used to examine infiltration, surface runoff and soil loss on natural forest, agricultural and grazing lands.The study found that there was a significant difference in the mean runoff rate and soil lost from the three land use practices. Soil loss increased as rainfall intensity increased.However, the highest mean runoff rate was recorded from grazing area followed by agricultural while forested area recorded the least runoff rate.These results are useful in prioritizing interventions for land and water management 96 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The management of sediments in river basins and waterways has been an important issue for water managers throughout history. Water Engineers and managers are faced with similar challenges caused by siltation of water reservoirs and irrigation water conveyance systems. As a copping strategy to counter the low irrigation application efficiency, designs of settling tanks are typically oversized. This is aimed at having enough detention time for the sediment particles to settle. This process is costly and tedious hence this book is aimed at optimizing the hydraulic design parameters for settling basins with an intention of addressing such challenges. Artificial Neural Networks in MATLAB was used to build ANN models for predicting sediment settlement and eventually optimizing the hydraulic parameters of settling basins. The ANN was used to develop the relation between sediment settlement and different inflows by changing the different number of neurons in hidden layer. The developed simulated results were evaluated using recommended quantitative statistical analysis that compared the measured and the predicted data.…
