Abstract

The Tambak Anyar polder is one of the many traditional polders scattered in the Banjar Regency. Nevertheless, this polder is flooded almost every year. The purpose of this research is to evaluate dependable discharge that entering to polder system that can be supported by the river capacity inside the polder for flood mitigation. The method used to estimate the water availability is the Mock Model. Furthermore, the data needed are observed discharge, rainfall, and evapotranspiration data. The results of water availability analysis shown that the maximum dependable flow Q80% obtained is 4.89m3/s in the 1st period of January, and the minimum dependable flow Q80% is 1.37 m3/s in the 2nd period of September. The discharge entering the polder is quite large; the capability of Tambak Anyar River as a conveyor channel only can collect 29.74% from the dependable discharge, while the Rantau Bujur River only can accommodate 7.47% in April. In May, Tambak Anyar River's capability can only collect 7.17% from the dependable discharge, while the Rantau Bujur River can only accommodate 0.81%. The amount of discharge cannot be supported by the conveyor river inside the polder. The paddy fields in the Tambak Anyar polder often overflow caused by excess water. This excess of water caused floods that inundated the polder area and the other areas in Banjar Regency as of the beginning of January 2021. The amount of water that has access to the polder is not counterbalanced by watergates facilities and infrastructure management.

Abstract

Urban growth is inseparable from the development of settlements, city facilities and infrastructure, and other supporting facilities. Urban growth also occurs in Balangan Regency, especially in Balangan City. The development of urban planning is inseparable from the hydrological factor of the area. This study aims to evaluate the existing water system in Balangan City on the hydrological aspects of the area, especially in the office area and city growth. The evaluation includes the existing water system in Balangan City, the existing conditions, and how to plan for the future. This study proves that the air system's condition, especially the drainage system in Balangan City, is not well integrated, which is indicated by the absence of a comprehensive network system, making it difficult to evaluate the existing air system. Fortunately, this can still be covered by the hilly topography of Balangan City and the land use that is still not compacted so that water infiltration into the ground can still be expected as a solution. The need for an integrated system by taking into account urban open spaces.

Abstract

Liang Anggang Protected Forest is an area formed from peatland. Peatlands have a role in conserving water resources, reducing floods, preventing seepage of seawater, and so on. Damage to the water system in peatlands is often caused by individual activities that are not well controlled. This is thought to have resulted in the depletion of water in the peat soil, making the soil dry and flammable in the dry season. This research aims to analyze the rate of infiltrated water in the Liang Anggang Block 1 Protected Forest area. It was also found that the volume of infiltrated water in the natural conditions of the protected forest, assuming that there is no current use of the protected forest area, is 9,097,126.998 m3/year, and the total after there is current utilization of 8,498,889.127 m3/year. Due to the current utilization carried out in the area under review, the infiltration volume value decreased by 6.576%. Based on this research, it is very necessary to maintain land use in the Liang Anggang protected forest to maintain the volume of infiltrated water in the area.
