The principles of remotely sensing sea surface salinity are brietly reviewed, The airborne instrument used for this study is a Scanning Low Frequency Microwave Radiometer (SLFMR). It has spatial resolution of typically 500m (depending on the altitude of the aircraft) and a salinity resolution of about I psu, This configuration is suitable for studying the dynamics of river plumes as they form o...

water quality trading is a new approach in pollution control which satisfies water quality standards suggesting minimum cost solutions. this method uses tradable discharge permits based on pollution transfer coefficient in a river. this paper tries to establish a water quality trading program in a river basin according to transfer coefficients between pollution sources and evaluate cost effecti...

The paper contains data about the destructive effects of gully erosion on the environment. It provides general information about the gully erosion in several countries around the world including Romania and is considered a case study for a river basin located in the Semenic Mountains (Bârzava drainage area). The case study is based on the following assumptions: the presence of different types o...

The paper aims at evaluating the effects of heavy groundwater withdrawal and artificial groundwater recharge of an exmining pond to the aquifer system of the Langat Basin through the three-dimensional (3D) numerical modeling. Many mining sites have been left behind from the massive mining exploitations in Malaysia during the England colonization era and from the last few decades. These sites ar...

background the non-revenue water refers to a difference between the volume of water entering the system and billed authorized consumption. objectives the main purpose of this study is to determine the volume of non-revenue water in order to recognize the factors influencing water losses so that the information gathered can used in non-revenue water reduction management. materials and methods ka...

In the past 30 years efforts to protect river beds and banks have increased significantly. The selection design of proper structural solution means finding a in accordance with construction principles, geomorphology, avoiding channel aggradation, bed scour, bank erosion, resulting structure failure significant harm stream nearby property. On other hand, should be environmentally-friendly. Hydra...
