“…Land cover map was obtained by digitizing IKONOS image from Google Earth (Basuki et al, 2017b). Based on the previous analysis, the land cover of the study site can be differentiated into old and young teak plantations, paddy field (sawah), dryland agriculture, shrub, water body, mixed garden, and settlement (Basuki et al, 2017b).…”

:Quantifying sediment is essential to determine its sources and reduce its negative impacts. A study was conducted to quantify suspended sediments of catchments covering by teak plantation and to provide alternatives soil conservation practices. Five catchments with old teak coverages of 82, 82, 74, 70, and 53 % were chosen. At the outlet of each catchment was installed tide gauge to monitor stream water level (SWL). Water samples for sediment analyses were taken for every increament of SWL. Sediment yield was calculated based on rating curves of sediment discharge. The results showed that the sources of sediment in the streams were dryland agricultural and streambank erosion. The mean annual sediment yield during the study were 9.3, 10, 15, 53.3, and 22.5 t/ha for catchments covered by old teak plantation of 82, 82, 74, 70, and 53 %, respectively. To reduce sediment yield some soil conservation practices must be applied. Conservation of soil organic matter is important in order to stabilize soil aggregate and prevent clay dispersion which causes erosion and sedimentation. Green firebreaks or making channels are needed to prevent fire during dry season and organic matter loss. Stabilization of streambank is neccesary, either using vegetative method or civil technics.

“…It does not only affect the quantity of water yield, but also water quality, and continuity. Forests or other vegetative permanent control peak discharge until a certain rainfall event [6]. Therefore, the reduction area of vegetative permanent may reduce infiltration of rainfall into soils and increase direct surface flow that causes flood [7][8][9][10].…”

Rainfall is one of the factors affecting stream water discharge and flooding. The high amount and intensity of rainfall frequently cause downstream flooding. In this regard, a study with the purpose to know the trend of rainfall, discharge, and land cover of Kaligarang or Garang Watershed was conducted. Kaligarang Watershed is located in Central Java, Indonesia. Secondary data were collected from published papers and related institutions. Land cover data were derived from Landsat images. A regression analysis was conducted to observe the trend of maximum rainfall and peak discharge. The simple regression was conducted between the time and maximum rainfall or peak discharge within the corresponding year. The results showed that maximum daily rainfall 1972-1980 tended to increase. Maximum daily rainfall from 1981 to 1990 slightly decrease, however, extreme rainfall occurred in 1990. Compared to the data 1972-1980, the maximum rainfall in the period of 1991-2010 was lower. The peak discharge of the period 1961-1970 tended to decrease, conversely, starting 1971 to 2017, the peak discharge tended to increase. The reduction of the dryland forest and plantation forest were observed from every decade starting from 1990, in contrast, the settlement increased 138% from 1990 to 2020.

“…Flooding does not only occur in urban areas, but it can happen in rural areas and even in watersheds covered by large forests. Heavy rain in forested watersheds will cause saturation on the forest floor (Basuki et al, 2017). In this situation, rain water cannot enter into deeper soil layers, and all of the rain water becomes direct runoff.…”

Flood is a natural disaster that frequently happens and causes many material and immaterial losses. During flooding, the suspended sediment is carried along by the streamflow. The amount of sediment transported varies and depends on natural and anthropogenic factors. Limited studies have been conducted regarding the relationship between peak flood volume and its sediment content. Therefore, a study with the purpose to understand the relationship of rainfall characteristics, peak flood volume, and suspended sediment was undertaken in Kedungbulus Catchment in Gombong, Central Java, Indonesia. The size of Kedungbulus catchment is 37.8 km2. To collect the required data, an automatic stream water level recorder was installed in the outlet of the catchment. In addition, an automatic and two conventional rain gauges were set up inside the catchment. Hydrograph and statistical analysis were conducted on 2016-2017 data. The results showed that during the study period, the highest peak flood volume occurred on October 8, 2016. The flood duration was 490 minutes, with the time to peak was 135 minutes. At the highest peak flood volume, the stream water was 5,091,221 m3, and the suspended sediment was around 2,394 tons. Rainfall depth significantly affects the peak flood volume and its suspended sediment. The rainfall intensity and Antecedent Soil Moisture Content (ASMC) weakly correlate with peak flood volume and its suspended sediment content.
