“…The diverted water discharge of each irrigation canal in the MBBRIS was converted to a flow duration curve (FDC). The flow duration curve is a graphical presentation of the water flow over time and places with the highest figures on the left, and the lower figures are placed progressively over to the right [11]. The FDC was used to estimate the water power that could be generated.…”

“…The water power capacity of each existing irrigation canal was computed considering the available irrigation heads of the canals and the 40% of the time the water discharge equaled or exceeded. Water power capacity was characterized into kilowatts (kW) and was computed using equation ( 1) below [11,12].…”

“…The physical characteristics of the river were observed in each cross-section of the river segment. Water velocity and discharge were measured by floatation method [11]. The physical characteristics of the river segments were described in terms of sediment type of the channel bed, river width, floodplain, height of the river bank, and river depth.…”

The study was conducted to illustrate the physical profile of the three major rivers of Eastern Samar inside the SINP to serve as a reference for the river landscape. Highlights of the profile are river width, depth, water velocity and water flow rate, potential source, river stretch, flood height and flood plain as inputs to development and disaster planning. Data presented here were based on field surveys supported and guided by reference maps. Based on the survey, a potential source of Oras and Ulot-Can-avid Rivers is San Jose de Buan, Samar while Suribao River flows from the closed-canopy forest from Borongan-Maydolong-Llorente (Eastern Samar). Flooding and erosion were observed in the three rivers, but the highest silt deposits and the widest flood plain were in Oras River, with the highest water flow rate in the upstream. Erosion and quarrying were observed in all rivers. Bamboo reforestation is conducted in Suribao River as river bank erosion control measures. Results of the survey revealed the high risk to our rivers and river villagers due to flooding and erosion, in addition to the loss of properties and livelihood, and the ecological conservation of the landscape. Collective rehabilitation measures should be crafted for a unified action to address environmental issues parallel to development plans to promote but sustainably manage our resources and protect our villagers.

“…The rainfall precipitation considered in this study was a 23-year rainfall data from 1990-2012 [7]. Computations used the Microsoft Excel that determines the rainfall precipitation duration curve (RPDC) of each station [8]. Rainfall precipitation was evaluated and computed into rainfall precipitation curve, which determined the rainfall precipitation percentage of time equaled or exceeded.…”

“…Method of RPDC is the same as flow duration curve when river flow was considered to be a source of energy [8]. It is by taking all the rainfall precipitation records over the year and placing them with the highest figures on the left and the lower figure placed progressively over to the right.…”

The Philippines is in a tropical location where rainwater is abundant for the frequent rain in a year. Rainwater becomes waste flowing down the drains causing flood, especially in urban areas. This problem initiates local governments in some cities in the Philippines to adapt and implement Green programs that require the installation and utilization of rainwater catchment system. Though this program addresses the control of flood caused by the rain, the generation of energy by utilizing rainwater as an energy source is not yet considered. With this, the study computes the equivalent energy generation by utilizing rainwater. The rainwater energy equivalent includes the following: the increasing number of high-rise building construction as catchment facility; the rainfall precipitation of 58 stations in the Philippines; the floor area and the types of the building; and the volume of water consumption per person per day. The energy equivalent was computed using the 40% of the time the rainfall precipitation equaled or exceeded the other with the average floor area specified from the approved building permit as of 2017. The study established a mathematical equation as an equivalent energy of rainwater utilization. The equation of energy equivalent was derived using the initial building height of 5 meters and an additional succeeding height of 3 meters per floor level.
