This study quantifies some of the potential impacts climate change and nutrient pollution to identify most important factors on water quality changes algal blooms in region. Three variables, air temperature streamflow, representing change, runoff, were varied eight hypothetical scenarios determine their impact by calibrated validated model QUAL2K. Water was assessed concentrations dissolved oxy...

QUAL2K merupakan instrumen yang paling banyak digunakan dalam menyimulasikan kualitas air sungai di Indonesia. Untuk mengoperasikannya, membutuhkan input dari berbagai parameter dan variabel dengan jumlah sehingga pengguna biasanya menggunakan nilai default untuk menyederhanakan proses simulasi. Namun, kesesuaian penggunaan deafult ini pada kasus Indonesia belum pernah dievaluasi. Penelitian be...

Drought reduces the quantity and quality of water resources ultimately increases risk agricultural activities at farm level. Therefore, by developing risk-based economic models, effects changes in on farmers' decisions should be examined. In this regard, drought farmers Qazvin Plain Irrigation Network have been evaluated. For purpose, firstly, river flow was simulated using Qual2k model 1998–20...
