Laboratory apparatuses for the analysis of infiltration and runoff enable studies under controlled environments at reduced costs. Unfortunately, design construction such systems are complex face difficulties associated with scale factor. This paper presents design, construction, evaluation a portable rainfall simulator. The apparatus allows unsaturated soils without vegetation cover, wide range...

This paper presents an evaluation of the performance of the Massachusetts Institute of Technology (MIT) regional climate model (MRCM) in simulating the West African monsoon. The MRCM is built on the Regional ClimateModel, version 3 (RegCM3), but with several improvements, including coupling of Integrated Biosphere Simulator (IBIS) land surface scheme, a new surface albedo assignment method, new...

Steep slopes consisting of disturbed soil are very often found in construction, landfill, and surface mining situations. Although legislation and economics dictate that vegetative cover be established on these slopes as rapidly as possible, the occurrence of large rainfall events during critical periods of vegetation establishment can frequently cause extensive soil loss. Sediment generated fro...

Kahgel is one of the oldest traditional mortars in Iran capabilities and performance of which in the past to conserve earthen buildings show that it can be used as a covering for conservation and preservation of earthen architectural structures. The ancient waterproof covering is very efficient at keeping the building dry during the heavy rain showers, but low durability and the need for renewa...

Tillage system effect, Conventional (CT) vs. No-Till (NT), on soil physical properties and Br transport was studied at two locations in North Carolina. The soil types were a Typic Paleudults at Coastal Plain (site 1) and a Typic Kanhapludults at Piedmont (site 2). Bulk density (BD), total porosity (TP), macroporosity (MP), and saturated hydraulic conductivity (Ks) .were measured in plant row (R...

Precipitation is an important component of the Earth’s water cycle and needs to be carefully monitored. Its large variability over a wide range of spatial and temporal scales must be taken into account. For example, hydrological models require accurate rainfall estimates at high spatial and temporal resolutions (e.g., 1 km and 5 min or higher). Obtaining accurate rainfall estimates at these sca...
