Abstract This paper presents a study of 98.1 kW-PV system facing south at an inclined angle 15º on the roof university building in Seoul, South Korea (latitude 37.63° N and longitude 127.1° E). The performance was analyzed for 2 years from Sep. 2015 to Aug. 2017. average electrical power output 0.59 kWh/(m ·day) with 16.9% annual efficiency 1st year which further decreased 0.58 17.6% 2nd year. ...

Rainfall-runoff processes in a small oil palm catchment (8.2 ha) in Johor, Malaysia were examined. Storm hydrographs show rapid responses to rainfall with a short time to peak. The estimated initial hydrologic loss for the oil palm catchment is 5 mm. Despite the low initial loss, the catchment exhibits a high proportion of baseflow, approximately 54% of the total runoff. On an event basis, the ...

The development of catchment modelling tools has gained considerable momentum through the Cooperative Research Centre for Catchment Hydrology’s Catchment Modelling Toolkit. This repository of models (see www.toolkit.net.au) allows the modeller to select the most appropriate tools with which to best represent their catchment and associated constituent processes. While this has improved the abili...

A decline in marine water quality entering the Great Barrier Reef (GBR) lagoon is associated with terrestrial runoff discharged from adjacent GBR catchments. Reef Plan 2013 outlines water quality targets to address this decline, with the eWater CRC Source Catchment modelling framework used to report progress towards meeting these targets. Catchment modelling is an ideal tool to investigate cons...

The mean annual transfer (loss and retention) of nitrogen in a river system was estimated using a conceptual approach based on water surface area and runoff. Two different approaches for the calculation of water surface area were applied to determine riverine nitrogen retention in four European catchments, ranging between 860-14,000 km2 in area, and differing considerably in the proportion and ...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Dissolved organic carbon concentrations ([DOC]) in surface waters are increasing in many regions of Europe and North America. These increases are likely driven by a combination of changing climate, recovery from acidification and change in...

Rooftop solar photovoltaic(PV) installation in India have increased lastdecade because of the flat 40 percent subsidy extended for rooftop solarPV systems (3 kWp and below) by Indian government under solarrooftop scheme. From residential building owner’s perspective, PVis competitive when it can produce electricity at a cost less than or equalgrid price, condition referred as “grid parity”. For...
