GIS models of the empirical methods Blaney-Criddle, Hammon, De Bruin and Makkink have been developed in ArcMap model-builder environment to estimate daily mean reference evapotranspiration (ETo). MODIS LST Day and Night products along with meteorological data were used as inputs. The application was on Peloponnese, Greece, for months December and August of years 2016-2019. For the validation of the models FAO Penman-Monteith (FAO-PM) was used as a reference. For the evaluation of the models Root Mean Square Error (RMSE), Mean Bias (MB) and Normalized mean Bias (NMB) were computed. Hargreaves-Samani's and Hansen's previous estimates were also employed. Hammon's estimates are closer to FAO-PM for December, with Hansen's following closely. Hargreaves-Samani model, followed by De Bruin model, produced the closest estimates to FAO-PM for August. It is noteworthy that the estimates for August were significantly better than those for December for all empirical models. This is probably because of negligible wind speed values in August. FAO-PM is sensitive in the wind speed values of December. The presented empirical models are quick and accurate and can employ LST inputs of any spatial resolution.

“…In this study, the inflow-outflow model (IOM) was slightly modified from the mass balance method to predict the variations of water depth in the lake. Blaney and Criddle method used to calculate the lake evaporation since the input data was only atmospheric temperature and suitable for data limitation case studies (Zhan et al, 2009).…”

Kandawgyi Lake is a famous recreational place in Yangon; however, the water quality deterioration and algae blooming occurred in recent years due to the economic development and people’s unawareness. In this study, the dynamic behaviors of water quality and mechanisms of eutrophication is investigated. During one-year field observation’s results showed that the lake’s water quality had been polluted by domestic wastewater depend on the high value of BOD and COD. Moreover, it was found that the thermal stratification exists about 1.0 meters water depth of the lake and anoxic water mass exists near the bottom of the lake. Besides, the one-year water depth observation showed the seasonal changes of water depth and, the water depth prediction by using the IOM mass balance model indicated better agreements in a dry season than a wet season. From the results of this study, it was thought that internal loading of nutrients could be the main reason of the algae blooms. Therefore, we proposed the bottom sediment removal as the most effective method to improve the water quality. Furthermore, small constructed wetlands at each inlet drains also can be an effective method as a countermeasure for the prevention of the next sediment accumulation.

The present study was conducted to investigate the residue status of two insecticides (acetamiprid and buprofezin) and their dissipation kinetics in three matrices viz. paddy grain, straw and soil. The extraction protocol for residues of these two insecticides was executed using acetonitrile solvent. The analytical method was validated, which showed good linearity with the limit of quanti cation (LOQ) value of 0.01 and 0.02 mg kg -1 for acetamiprid and buprofezin respectively. The recovery range was 79.67-98.33 % concerning all the matrices in both the insecticides. Acetamiprid (20% SP) and Buprofezin (25% SC) were applied separately in the paddy eld in two doses: single dose (recommended dose) and double dose along with untreated control throughout the experiment. Residue analysis of these two insecticides in paddy (grain and straw) and soil was accomplished employing high-pressure liquid chromatography (HPLC) with a UV detector. The dissipation data showed that acetamiprid exhibited higher dissipation in comparison with buprofezin. However, their persistence was found slightly higher in soil. The dissipation dynamics in the rice and soil were discussed with biological half-lives of both the insecticides. Consumer risk assessment study was also made considering its fate to the consumers.
