A study on water quality and hydrological factor of Beriah Swamp Perak and rivers entering and leaving the swamp was conducted from 6 June to 24 October 1998. The study was done in situ at three stations Beriah River B Beriah Kiri River BL and Beriah Kanan River BR involving the measurement of temperature dissolved oxygen total dissolved solid pH conductivity and hydrological factor such a stream velocity stream cross-sectional profile and humidity. Water analysis was done in vivo to determine orthophosphate ammonia dissolved nitrate and total suspended solid in order to assess the functions of swamp as sediment and nutrient trap as well as water purification. Results showed that water quality and hydrological parameters varies from station to station and a significant contrast between input and output stations was observed. Generally temperature ranged from 25.5 to 29.2 deg C. The pH were low at the outlet mean 4.29 compared to inlet 4.77-4.87. Conductivity was higher at the outlet by as much as 2-3 times whereas dissolved oxygen was reduced by almost half compared to the inlet. The mean total dissolved solid at the input sites were about 15.0 mg lE-1 compared to a higher mean of 35.7 mg lE-1 at the outlet. Total suspended solid were low but showed and increase of almost 2-6 times between the inlet and the outlet. River discharge varied from station to station with an average discharge of 4.32 triple m sE-1 2.31 triple m sE-1 and 1.26 triple m sE-1 for Beriah River Beriah Kiri and Keriah Kanan respetively. Suspended solids input was negligible about 3.7 kg kmE-2 and 1.4 kg kmE-2 for BR and BL respectively whereas the output into the Beriah River was 7 kg kmE-2. The dissolved nutrients inputs were the highest with the total input of 21 289 kg kmE-2 at BR 19 096 kg kmE-2 at BL and an output of 42 156 kg kmE-2 at the outlet B. The order of abundance for the dissolved loads was nitrate ammonia phosphate. The results showed that in general the dissolved loads are generated and flushed out of the swamp ecosystem. Individual evaluation of the nutrient shows that the nitrogen component nitrate and ammonia was retained in the wetland system whereas phosphate was added in the swamp and flushed out. The way in which nitrate and ammonia was transported shows that Beriah swamp does act as a nutrient trap as has been observed elsewhere.

Abstract

A study on water quality and hydrological factor of Beriah Swamp Perak and rivers entering and leaving the swamp was conducted from 6 June to 24 October 1998. The study was done in situ at three stations Beriah River B Beriah Kiri River BL and Beriah Kanan River BR involving the measurement of temperature dissolved oxygen total dissolved solid pH conductivity and hydrological factor such a stream velocity stream cross-sectional profile and humidity. Water analysis was done in vivo to determine orthophosphate ammonia dissolved nitrate and total suspended solid in order to assess the functions of swamp as sediment and nutrient trap as well as water purification. Results showed that water quality and hydrological parameters varies from station to station and a significant contrast between input and output stations was observed. Generally temperature ranged from 25.5 to 29.2 deg C. The pH were low at the outlet mean 4.29 compared to inlet 4.77-4.87. Conductivity was higher at the outlet by as much as 2-3 times whereas dissolved oxygen was reduced by almost half compared to the inlet. The mean total dissolved solid at the input sites were about 15.0 mg lE-1 compared to a higher mean of 35.7 mg lE-1 at the outlet. Total suspended solid were low but showed and increase of almost 2-6 times between the inlet and the outlet. River discharge varied from station to station with an average discharge of 4.32 triple m sE-1 2.31 triple m sE-1 and 1.26 triple m sE-1 for Beriah River Beriah Kiri and Keriah Kanan respetively. Suspended solids input was negligible about 3.7 kg kmE-2 and 1.4 kg kmE-2 for BR and BL respectively whereas the output into the Beriah River was 7 kg kmE-2. The dissolved nutrients inputs were the highest with the total input of 21 289 kg kmE-2 at BR 19 096 kg kmE-2 at BL and an output of 42 156 kg kmE-2 at the outlet B.
