Comparing WEPP and Hydro Physical Models to Estimate Soil Erosion and Sediment Production: A Case Study of Chardavol Watershed
Extended abstract 1- Introduction Soil erosion and sediment production include fundamental limitations in the use of soil and water resources. The sediment yields watersheds in addition to the loss of soil fertility, causing water quality reduction. Therefore, evaluation processes that govern their behavior to better understand and assess the systems of watershed management practices are imp...
متن کاملThe Potential of Waste Stabilization Ponds Effluent as a Liquid Fertilizer
This research investigation was aimed at demonstrating the technical and economic feasibility of waste stabilization ponds (WSP) under the climatic conditions of a subtropical region. A pilot plant was designed and constructed at the Karachi University Campus (KUC) for the treatment of domestic wastewater. An intensive analytical programme was followed for 24 months to evaluate the performance ...
متن کاملMicroplastics in water, sediment and salts from traditional salt producing ponds
Plastic pollution has universally known accumulated in all environment compartments and accelerating threat to the sustainability of earth. Field survey to examine the occurrence of microplastics in ancient sea water evaporation technology of ponds at Pallengu-Jeneponto, was conducted. From this sea salt producing ponds, samples of water, sediment and freshly harvested salts were collected. Six...
متن کاملa study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
Nitrogen transformations and balance in channel catfish ponds
A nitrogen (N) budget was developed for four, 400-m ponds stocked with 550 channel catfish (Ictalurus punctatus) fingerlings that were fed to satiation daily for 133 days with a ration containing 4.85% N. Feed accounted for 87.9% of the N input to ponds. Abundant N from ammonia (NH3), ammonium (NH4 ), and nitrate (NO3 ) and the high total N: total phosphorus ratio in pond waters prevented appre...
