River Capacity for Sectoral Water Pollution Loads (Case Study: Cilamajang River) City of Tasikmalaya

technical and legal parameters for determination of river boundary,( case study haraz river)

چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...

Land Use Planning for Urban River Margins Based on the Green City Approach (Case study: Abshooran River of Kermanshah)

Physical development without proper planning has limited ecological capacity and the ability of natural ecosystems. Urban river structure as one of the most important ecological infrastructures in the city provides a variety of ecosystem services, including landscaping, climate change, etc. which is strongly dependent on the structure and functional status of the river. This study was conducted...

Source Apportionment of Annual Water Pollution Loads in River Basins by Remote-Sensed Land Cover Classification

In this study, in order to determine the efficiency of estimating annual water pollution loads from remote-sensed land cover classification and ground-observed hydrological data, an empirical model was investigated. Remote sensing data imagery from National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer were applied to an 11 year (1994–2004) water quality...

1 WATER POLLUTION TRADING SYSTEMS FOR IMPROVED RIVER WATER QUALITY : The Case of Unlike Pollutants

Comparison and evaluation of intelligent models for river suspended sediment estimation (case study: Kakareza River, Iran)

Sediment transport constantly influences river and civil structures and the lack ofinformation about its exact amount makes management efforts less effective. Hence,achieving a proper procedure to estimate the sediment load in rivers is important. We usedsupport vector machine model to estimate the sediments of the Kakareza River in LorestanProvince and the results were compared with those obta...
