Abstract. The Riparian Channel and Environmental (RCE) inventory was developed to quickly assess the physical and biological conditions of small streams in lowland, agricultural landscapes in temperate regions that have been physically modified. Furthermore, the inventory was developed to assess physical disruption of the channel and riparian zone. There were three sites used to conduct the study which measure 2 kms and 4 kms upland and 2 kms downland from the origin point which is the bridge. Water samples were taken from each site. Physico-chemical testings were used to assess the sample. Results revealed that the Lun Padidu river is under the classification of very good status for the RCE and the data results of the water samples showed that the water is suitable for the convenience of living.
Key Words: riparian zone, physico-chemical parameters, riparian channel and environmental inventory.
Introduction. The Philippines is surrounded by bodies of water: seas and oceans. Along the 7,100 islands, there are streams, lakes, swamps and rivers and other bodies of water which are the source of sustainable water for irrigation and fish culturing industries. These bodies of water support the diverse wildlife species and humanity. Furthermore, they help to maintain the ecological balance in a community specifically in agricultural lands. Since Philippines is an agricultural country, one of its primary concerns is to maintain the preservation of rivers which is the primary source of water. The importance of knowing the status of the water and the riverbanks will help to establish proper practices to avoid pollutions to maintain the stability of the river.
Physico-chemical parameters work together with the biological indicators in determining water quality. These parameters are dissolved oxygen (DO), power of hydrogen (pH), temperature (T), total dissolved solids (TDS) and salinity. The dissolved oxygen parameter is one of the most important indicators of the quality of water foraquatic life. It is essential for all plants and animals. Oxygen availability throughout the year is influenced by other chemicals present in the water, biological processes, and temperature. A dissolved oxygen test measures the amount of oxygen dissolved in the water. A dissolved oxygen measurement, however, does not measure the amount of disolved oxygen the water is capable of holding at the temperature at which it was tested....
