Geographic Information System (GIS) based soil loss estimation using Universal Soil Loss Equation Model (USLE) for soil conservation planning in Karesa Watershed, Dawuro Zone, South West Ethiopia

Soil erosion is the most challenging and continuous environmental problems resulting in both on-site and off-site effects in the world particularly in Ethiopia. Karesa watershed is one of the most erosion-prone watersheds which received little soil conservation attention. This study was conducted to estimate average annual soil loss rate using Geographic Information System and Universal Soil Loss Equation Model adapted...

Spatial and temporal fluctuation of groundwater depth in Amibara, middle Awash, Ethiopia

Soil salinity is a  threat  for agriculture under irrigation as it affects the growth and development of plants and the problem is widespread in middle Awash where Amibara irrigated farms are present. Therefore, Measurements of groundwater depth were taken from thirty piezometers in the months of August, September, October, November and December to investigate spatial variability and temporal fluctuation of...

Estimate of bed load transport and scour depth in Kwadna watershed in Minna, Niger State, Nigeria

Knowledge of sediment transport has been used to determine whether erosion or deposition will occur beneath the hydraulic structures, especially the magnitude of this erosion or deposition, and the time and distance over which it will occur. This paper, utilizes the stream gauging by wading method in estimating the bed load transport and scour depth in Kwadna Basin. The estimate of bed load transport enhances the...
